🌐 Web query:

Buf CLI registry module label list --format json next_page pagination response

💡 Result:

The buf registry module label list command supports pagination when using the --format=json flag [1][2]. When you request JSON output, the API response includes a next_page key if there are additional results available [1][3]. You can use this value as the argument for the --page-token flag in subsequent commands to retrieve the next set of data [1][2][4]. Key flags related to pagination and output include: --format string: Set to json to enable the pagination response structure [1][2]. --page-size uint32: Controls the number of items returned per page [1][2]. --page-token string: Used to request a specific page of results using the token provided in the previous response [1][2]. Example usage pattern: buf registry module label list <remote/owner/module> --format json --page-size 10 If the result contains a "next_page" value, you would follow up with: buf registry module label list <remote/owner/module> --format json --page-size 10 --page-token <next_page_value>

Read all pages before selecting the latest label.

With --format json, buf registry module label list returns next_page when more labels exist. This workflow reads only .labels, so it can select an older version when the latest label is on a later page. Follow next_page with --page-token before running sort -V.

the BSR_LABEL workflow logic around the buf registry label listing to retrieve
and combine every page, following each response’s next_page token via
--page-token until no further page exists, then extract semantic version labels
and apply the existing sort -V and tail selection to the complete set.
